About this file
This set of engineering drawings and documents outlines specifications for upgrading pump stations along the Columbia River in Oregon and Washington as part of solicitation number W912EF23B0002 from the U.S. Army Corps of Engineers Walla Walla District. The upgrades include replacing existing pumps and motors with new higher horsepower equipment at eleven pump stations, installing portable generator connections, upgrading electrical panels and switchgear, and performing other miscellaneous renovations and repairs. Key pump stations requiring upgrades are identified as 2C, 5D, 6B, 12-1/12-1A complex, 12-2, 15C, 15D, and 15E/15E1 complex. Electrical specifications include installing new service entrance rated manual transfer switches, motor control centers, transformers, and related infrastructure to support the upgraded pumping equipment. Completion is required by September 2023.
